Drexel Researchers Help Provide First Glimpse at Organelles In Action

Researchers at Howard Hughes Medical Institute and the Eunice Kennedy Shriver National Institute for Child Health and Human Development are getting a first glimpse at the inner-workings of live cells thanks to a new microscopy technique pioneered by Nobel laureate Eric Betzig with help from engineers at Drexel University. Their method uses grids of light that activate fluorescent color tags on each type of organelle — the result is a 3-D video that gives researchers their best look at how cells function. It will allow scientists to better understand how cells react to environmental stressors and respond to drug treatment.

Common Artificial Sweetener Likely a Safe, Effective Birth Control, Pesticide for Insects, Drexel Study Finds

Erythritol, a non-nutritive sweetener found in products like Truvia, has proven effective in killing fly larvae and slowing down their egg production, making it a good candidate for human and pet-safe pesticide use.

Q&A With Paul W. Brandt-Rauf, Dean of the School of Biomedical Engineering, Science and Health Systems

The inaugural dean of the School of Biomedical Engineering, Science and Health Systems has only been on campus since February, but he’s already brimming with ideas to grow the school to have a bigger presence on campus and an even better reputation in its field. Paul W. Brandt-Rauf, MD, DrPH, ScD, the newest dean at Drexel, discussed all of these ideas and then some during a conversation with Drexel Quarterly in his new office.
Students attempt to negotiate a climate change agreement.

Drexel Students Try to Negotiate a Climate Change Accord

Three-dozen Drexel students role-played as global climate officials during a recent classroom exercise, working together to hash out a plan to address the changing environment. Over the course of nearly three hours of negotiations, they developed an agreement to reduce climate change and learned just how challenging such an endeavor can be.

A Recipe For Concrete That Can Withstand Road Salt Deterioration

Road salt, used in copious helpings each winter to protect them from ice and preserve safe driving conditions, is slowly degrading the concrete they’re made of. Engineers have known for some time that calcium chloride salt, commonly used as deicer, reacts with the calcium hydroxide in concrete to form a chemical byproduct that causes roadways to crumble. A civil engineer from Drexel University is working on a new recipe for concrete, using cast-off products from furnaces, that can hold its own against the forces of chemical erosion.

CDC/WHO Ebola Guidelines Could Put Sewer Workers at Risk

Research from Drexel University and the University of Pittsburgh suggests that guidelines for safe disposal of liquid waste from patients being treated for the Ebola virus might not go far enough to protect water treatment workers from being exposed. In a study recently published in the journal Water Environment Research, a group of environmental engineering researchers reports that sewer workers downstream of hospitals and treatment centers could contract Ebola via inhalation — a risk that is not currently accounted for in the Centers For Disease Control and Prevention or World Health Organization Ebola response protocol.
